逆冲推覆构造锋带及运移方向的确定标志

    CRITERIA FOR THE DETERMINATION OF THE LOCATION OF THE FRONTAL ZONE AND VERGENCE OF MIGRATION OF THE NANCHANG-YIFENG THRUSTNAPPE STRUCTURE

    • 摘要: 本文结合南昌—宜丰逆冲推覆构造的研究,综述了飞来峰的带式产出、顶板逆冲断层的强烈弯曲等,确定峰带位置的十条标志和判定逆冲运移方向的宏观构造(方箭原则、前断坡和褶皱倒向等)及微观构造(拉伸线理和旋转碎斑系等)标志。在简述控制剪切指向构造形态的因素的基础上,强调了利用小、微构造判定运移方向时应该注意的一些问题。

       

      Abstract: On the basis of the study of the Nanchang-Yifeng thrust nappe structure, the paper discusses the occurrence of klippen in a belt and strong bending of the hanging-wall thrust and also ten criteria for determination of the location of the frontal zone of the thrustnappe structure and macrostructures and microstructures for the identification of the vergence of thrusting. On the basis of the study of the factors for controlling the shearsense structural pattern, the paper emphasizes some problems that attention should be paid to in identifying the vergence of migratienusing small and micro-structures.
